Security challenges and opportunities in emerging device technologies
Speaker: Prof. Nele Mentens, Leiden University, The Netherlands & KU Leuven, Belgium
Date/Time: Jan 27th (Friday) at 16:00 HKT
Abstract: While traditional chips in bulk silicon technology are widely used for reliable and highly efficient systems, there are applications that call for devices in other technologies. On the one hand, novel device technologies need to be re-evaluated with respect to potential threats and attacks and how these can be faced with existing and novel security solutions and methods. On the other hand, emerging device technologies bring opportunities for building future security systems. This talk will give an overview of the minimal hardware resources that are needed to build secure systems and discusses the state-of-the-art in design of these hardware resources in emerging device technologies.

Edge Intelligence: Hardware Challenges and Opportunities
Speaker: Prof. Jose Nunez-Yanez, Linköping University, Sweden
Date/Time: Dec 2th (Friday) at 16:00 HKT
Abstract: In this talk we will initially discuss some basic edge computing concepts followed by the hardware challenges and opportunities of performing deep learning at the edge. We will then present the FADES (Fused Architecture for DEnse and Sparse tensor processing) heterogeneous architecture focusing on its application to Graph neural networks (GNN) acceleration. GNNs can deliver high accuracy when applied to non-Euclidean data in which data elements do not fit into a regular structure. They combine sparse and dense data characteristics and this, in turn, results in a combination of compute and bandwidth intensive requirements challenging to meet with general purpose hardware. FADES is a highly configurable architecture fully described with high-level synthesis integrated in TensorFlow Lite and Pytorch. It creates a dataflow of dataflows with multiple hardware treads and compute units that optimize data access and processing element utilization. This enables fine-grained stream hybrid processing of sparse and dense tensors suitable for multi-layer graph neural networks.
Biography: Prof. Nunez-Yanez is a professor in hardware architectures for Machine Learning at Linköping University with over 20 years of experience in the design of high-performance embedded hardware. He holds a PhD in hardware-based parallel data compression from the University of Loughborough, UK, with three patents awarded on the topic of high-speed parallel data compression. Previously to joining Linköping University he was a reader (associate professor) at Bristol University, UK. He spent a few years working in industry at ST Micro (Milan), ARM (Cambridge) and Sensata Systems (Swindon) with Marie Curie and Royal Society fellowships. His main area of expertise is in the design of hardware architectures and heterogenous systems for signal processing and
machine learning with a focus on run-time adaptation, high-performance via parallelism and energy-efficiency.
FPGA Technology: from Chips to Tools to Systems
Speaker: Prof. Dirk Koch, Heidelberg University
Date/Time: Nov 4th (Friday) at 16:00 HKT
Abstract: The Novel Computing Technologies (NCT) group at Heidelberg University works on mostly technology-focused aspects of reconfigurable computing. Our group maintains the open FABulous eFPGA framework which was used for the tape out of 10 chips so far. With that tool, we designed FPGA fabric clones of established Xilinx and Lattice FPGAs but also new fabrics that use memristor technology for configuration storage. Our GoAhead Partial reconfiguration tool allows the implementation of very adaptive FPGA systems where the FPGA resource utilization can be dynamically adjusted according to runtime requirements and operational conditions in a transparent manner, We use that to build a dynamic database processing system where accelerator modules are plugged together to processing pipelines for accelerating problems, that are only known at runtime. We also develop a security infrastructure that is required to operate FPGAs in data centers, and the talk will show how we crashed over 100 AWS F1 (FPGA) instances. More importantly, the talk will present the FPGADefender virus scanner that helps to prevent such attacks. Note that we vacant positions.
Biography: Dirk Koch is a Professor at the Heidelberg University. His main research interests are on run-time reconfigurable systems based 0n FPGAs. embedded systems, computer architecture, VLSI, and hardware security. Dirk developed techniques and tools for self-adaptive distributed embedded control systems based on FPGAs. Current research projects include database acceleration using FPGA-based stream processing, HPC, and exascale computing. as well as reconfigurable instruction set extensions for CPUs and using FPGAs in data centers. Dirk Koch is the author of the book Partial Reconfiguration on FPGAs’and a co-editor of the book “FPGAs for Software Programmers”
